At last I found  the solution,though not direct but can say a workaround.
In Color>Hue/Saturation/Lightness......reduce saturation to @ (-)40  and
then increase vibrance to 70.This attends the over saturated skin tones
without affecting other colors.
This  gives almost same results which I get in GIMP by selecting 'red
instead of default master' in the 'hue-saturation tool' and reducing it's
saturation. 

Hope in future version the sliders in H/S/L tool will work only on selected
channel.

Regards.
